Glass wool is a commonly used insulating material with good thermal and thermal insulation properties. Glass wool is usually made into rolls or plates and other shapes, and is widely used in construction, ships, automobiles and other fields. Next, Utsen glass wool manufacturers will explain the physical characteristics of glass wool.

1. Low density

The density of glass wool is low, usually between 10-100 kg/m3. This makes it relatively lightweight in insulation materials and easy to transport and install. At the same time, the low density also helps to increase the softness and plasticity of the material, making it suitable for surfaces of various shapes and structures.

2, low thermal conductivity

Thermal conductivity refers to the ability of a material to conduct heat, and the thermal conductivity of glass wool is lower, usually between 0.030-0.050W/(m·K). This means that the glass wool can effectively reduce the transfer of heat and provide good thermal insulation performance. Whether in cold winter or hot summer, glass wool can help maintain a stable indoor temperature and reduce energy consumption.

3. Sound absorption coefficient

Glass wool also has excellent sound insulation properties. It can absorb and reduce the propagation of sound waves and reduce the impact of noise. The sound absorption coefficient of glass wool is usually between 0.6-1.0, which means that it is able to effectively absorb the sound generated in the surrounding environment. This makes it an ideal soundproofing material for the interior and exterior of buildings, providing a more peaceful and comfortable environment.

4. Fire resistance

Glass wool also has good fire resistance. It can withstand high temperatures of more than 400 ° C and is not easy to burn. This makes glass wool widely used in places with strict fire protection requirements, such as commercial buildings, industrial facilities and transportation vehicles.

5. Chemical stability

Glass wool has certain chemical stability. It has a certain resistance to acid, alkali and other chemical substances, and is not easy to be corroded. This allows the glass wool to maintain its performance and life in harsh environments.

Glass wool has the physical characteristics of low density, low thermal conductivity, excellent sound insulation, good fire resistance and chemical stability. These properties make glass wool a common and important thermal, thermal and sound insulation material.
